[0003] In practical use, the high-speed impact of nails on the wooden board during nailing generates significant impact force, which can easily cause the board to vibrate, shift, or even deform locally. This prevents the nails from being accurately driven into the intended position, affecting connection strength and product consistency. These problems are particularly pronounced when processing large, complex workpieces. Therefore, this paper provides a rotary nailing machine for fabricating wide-body foot blocks. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary nailing machine for the manufacture of wide-body foot blocks, so as to solve the problem in the prior art mentioned above that, in actual use, the nails impact the wooden board at high speed during the nailing process, which will generate a large impact force, easily causing the wooden board to vibrate, shift or even deform locally, resulting in the nails not being able to be accurately driven into the predetermined position, affecting the connection strength and product consistency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a rotary nailing machine for making wide-body foot blocks, including a nailing machine body 1, a nailing tube 2 fixedly installed at the output end of the nailing machine body 1, a fixing plate 3 fixedly installed on the outside of the nailing tube 2, a plurality of holes 4 opened on one side of the fixing plate 3, the holes 4 passing through the fixing plate 3 and extending to the other side, an auxiliary pressure plate mechanism 5 is provided inside the holes 4, the auxiliary pressure plate mechanism 5 includes a plurality of hydraulic devices 501, the hydraulic devices 501 are fixedly installed on the other side of the fixing plate 3, a telescopic rod 502 is provided inside the hydraulic devices 501, one end of the telescopic rod 502 passes through the holes 4 and extends to one side of the fixing plate 3, a pressing plate 503 is fixedly connected to the end of the telescopic rod 502, and a groove 504 is opened on the side of the pressing plate 503 away from the telescopic rod 502 for accommodating a buffer component.

[0022] A rubber sheet 505 is provided inside the groove 504. The outer side of the rubber sheet 505 is fixedly connected to the inner wall of the groove 504 to provide a flexible pressing surface. Several fixing blocks 506 are fixedly installed at the bottom of the groove 504. An air chamber 507 is opened inside the fixing block 506. A valve plate 508 is provided at the top of the air chamber 507. The outer side of the valve plate 508 is movably abutting against the inner wall of the air chamber 507 and can slide up and down in the air chamber. A pressure rod 509 is fixedly connected to the top of the valve plate 508. The top of the pressure rod 509 passes through the fixing block 506 and extends above it, and is fixedly connected to the support block 510. The top of the support block 510 is fixedly connected to the bottom of the rubber sheet 505, thus forming a buffer linkage structure controlled by air pressure. The elastic deformation of the rubber sheet 505 absorbs part of the impact force, and the air pressure adjustment of the air chamber 507 further buffers the remaining impact, preventing the wooden board from deforming due to overpressure.

[0023] During use, when the nailing machine body 1 is started and enters the nailing operation state, the control system first sends a signal to drive the hydraulic device 501, which is fixed on the other side of the fixed plate 3, to start working. The hydraulic cylinder inside the hydraulic device 501 pushes the telescopic rod 502 outward through the pressure of the hydraulic oil. One end of the telescopic rod 502 passes through the hole 4 on the fixed plate 3 and drives the pressing plate 503 fixed at its end to move towards the wood board to be nailed. At this time, the rubber sheet 505 set on the side of the pressing plate 503 away from the telescopic rod 502 first contacts the surface of the wood board to be nailed. Since the rubber sheet 505 has a certain elasticity and deformation ability, it can provide a flexible buffer when it contacts the wood board, effectively avoiding damage to the board surface caused by rigid contact. At the same time, the friction between the rubber sheet 505 and the wood board also plays a preliminary role in fixing and limiting the wood board, preventing it from sliding or shifting before nailing.

[0024] As the nailing action officially begins, the nailing machine body 1 drives the nail into the wooden board at high speed through the nailing tube 2. During this process, a large impact force is generated between the nail and the wooden board. This impact force not only acts on the nail itself, but is also transmitted to its surrounding area through the wooden board, which can easily cause the wooden board to vibrate, deform, or even displace. This problem is more pronounced on large and complex workpieces such as wide-body foot blocks. To solve the above problems, the auxiliary pressure plate mechanism 5 designed in this utility model plays a continuous role in the nailing process. When the wooden board vibrates slightly or deforms locally due to the impact force, the rubber sheet 505 at the bottom of the pressure plate 503 will deform accordingly. The deformation of the rubber sheet 505 will drive the support block 510 fixed at its bottom to move down synchronously, thereby pushing the pressure rod 509 connected to it to move downward.

[0025] The downward movement of the pressure rod 509 causes the valve plate 508 to move downward inside the air chamber 507, compressing the air volume in the air chamber 507 and causing the air pressure inside the air chamber to increase. As the air pressure increases, the valve plate 508 is subjected to a reverse force from the air pressure and gradually tends to a state of equilibrium. At this time, a dynamic balance relationship is formed between the air pressure inside the air chamber 507 and the external pressing load, thereby realizing the automatic adjustment function of the pressing force. Specifically, when the surface of the wooden board is relatively flat and the thickness is uniform, the deformation of the rubber sheet 505 is small, the air pressure change in the air chamber 507 is also small, and the pressure applied to the wooden board by the pressing plate 503 is relatively stable. However, when the surface of the wooden board is uneven, the thickness varies, or there are local depressions, the deformation of the rubber sheet 505 increases, the air pressure in the air chamber 507 increases accordingly, and the valve plate 508 rebounds upward under the action of air pressure, causing the pressure rod 509 and the support block 510 to move upward, thereby reducing the squeezing force of the pressing plate 503 on the wooden board and avoiding deformation or damage to the wooden board due to excessive pressure.

[0026] Furthermore, a sliding sealing fit structure is adopted between the valve plate 508 and the inner wall of the air chamber 507 to ensure smooth movement within the air chamber while maintaining good airtightness and preventing air pressure leakage from affecting the adjustment accuracy. This structure enables the auxiliary pressure plate mechanism 5 to make real-time dynamic responses and pressure adjustments according to the actual nailing conditions, thereby achieving adaptive pressing control for wood boards of different thicknesses and materials. Through the synergistic effect of the hydraulic drive and air pressure buffer linkage mechanism, the entire auxiliary pressure plate system can always apply a moderate and adjustable pressing force to the wood board during the nailing process, which not only ensures the stability of the wood board during the nailing process, but also avoids problems such as nailing deviation, nail bending, or wood board damage caused by overpressure or underpressure.

[0027] This utility model provides a rotary nailing machine for making wide-body foot blocks. By setting a fixed plate 3 on the outside of the nailing tube 2 of the nailing machine body 1, and setting an auxiliary pressure plate mechanism 5 on the fixed plate 3, the machine can assist in pressing the wooden board to be nailed during the nailing operation, thereby effectively preventing the wooden board from shaking or deviating when subjected to the impact force of nailing, and significantly improving the stability and accuracy of the nailing operation. Specifically, the auxiliary pressure plate mechanism 5 includes several hydraulic devices 501. The hydraulic devices 501 are fixedly set on one side of the fixed plate 3 and are used to drive the telescopic rod 502 to drive the pressing plate 503 to apply pressure to the wooden board. Before nailing begins, the pressing plate 503 has already contacted the surface of the wooden board through the rubber sheet 505 to form a pre-tightened state, preventing the wooden board from shifting due to accidental contact or slight vibration before nailing.

[0028] During the nailing process, the high-speed impact of the nails into the wooden board generates a significant force, which can easily cause local deformation, vibration, or even overall displacement of the board, especially noticeable on large workpieces such as wide-body piers. In this case, the pressing action of the auxiliary pressure plate mechanism 5 effectively counteracts some of the impact energy. By applying stable vertical pressure to the board, it firmly fixes it in the nailing area, preventing displacement or shaking, ensuring the nails are accurately driven into the predetermined position, improving nailing quality and structural stability. Furthermore, the pressing plate 503 has a groove 504 on the side away from the telescopic rod 502. A rubber sheet 505 is installed inside the groove 504. When the rubber sheet 505 contacts the surface of the wooden board, it provides flexible cushioning, preventing damage to the board surface due to rigid contact. Simultaneously, a fixing block 506 is also installed inside the groove 504. The fixing block 506 contains an air chamber 507, which houses a valve plate 508, a pressure rod 509, and a support block 510, forming an air pressure regulation system.

[0029] When the surface of the wooden board is uneven or has varying thickness, the deformation of the rubber sheet 505 will cause the support block 510 to move downward, which in turn pushes the pressure rod 509 and the valve plate 508 downward, compressing the air in the air chamber 507 and forming a reverse air pressure support. When the pressure reaches a certain value, the valve plate 508 automatically adjusts the air pressure balance, thereby achieving adaptive adjustment of the pressing force. This ensures that the pressing plate 503 always applies a moderate and stable pressing force to the wooden board, avoiding deformation of the wooden board due to excessive pressure or failure to effectively fix the wooden board due to insufficient pressure. In summary, this utility model, by setting up a reasonably structured and responsive auxiliary pressing plate mechanism 5, not only effectively prevents the wooden board from shaking or shifting due to impact during nailing, but also has multiple functions such as buffering, shock absorption, and adaptive adjustment, improving the stability, accuracy, and adaptability of nailing operations. It is especially suitable for the production and manufacturing of complex structural components such as wide-body foot blocks with large dimensions and multiple nailing points, and has good application prospects and promotional value.
